static opj_tgt_tree_t* LSE_CALL lsi::CTgt::tgt_create	(	LSINT32	_i32NumLeafSh,
		LSINT32	_i32NumLeafSv
	)		`[static]`

Create a tag-tree.

Parameters:

_i32NumLeafSh	Width of the array of leafs of the tree.
_i32NumLeafSv	Height of the array of leafs of the tree.

static LSINT32 LSE_CALL lsi::CTgt::tgt_decode	(	CBio::opj_bio_t *	_pbBio,
		opj_tgt_tree_t *	_pttTree,
		LSINT32	_i32LeafNo,
		LSINT32	_i32Threshold
	)		`[static]`

Decode the value of a leaf of the tag-tree up to a given _i32Threshold.

Parameters:

_pbBio	Pointer to a BIO handle.
_pttTree	Tag-tree to decode.
_i32LeafNo	Number that identifies the leaf to decode.
_i32Threshold	Threshold to use when decoding value of the leaf.

static LSVOID LSE_CALL lsi::CTgt::tgt_destroy ( opj_tgt_tree_t * _pttTree ) [static]

Destroy a tag-tree, liberating memory.

Parameters:

_pttTree Tag-tree to destroy.

static LSVOID LSE_CALL lsi::CTgt::tgt_encode	(	CBio::opj_bio_t *	_pbBio,
		opj_tgt_tree_t *	_pttTree,
		LSINT32	_i32LeafNo,
		LSINT32	_i32Threshold
	)		`[static]`

Encode the value of a leaf of the tag-tree up to a given threshold.

Parameters:

_pbBio	Pointer to a BIO handle.
_pttTree	Tag-tree to modify.
_i32LeafNo	Number that identifies the leaf to encode.
_i32Threshold	Threshold to use when encoding value of the leaf.

static LSVOID LSE_CALL lsi::CTgt::tgt_reset ( opj_tgt_tree_t * _pttTree ) [static]

Reset a tag-tree (set all leaves to 0).

Parameters:

_pttTree Tag-tree to reset.

static LSVOID LSE_CALL lsi::CTgt::tgt_setvalue	(	opj_tgt_tree_t *	_pttTree,
		LSINT32	_i32LeafNo,
		LSINT32	_i32Value
	)		`[static]`

Set the value of a leaf of a tag-tree.

Parameters:

_pttTree	Tag-tree to modify.
_i32LeafNo	Number that identifies the leaf to modify.
_i32Value	New value of the leaf.
